A CT mig vid

Copy the link below to your browser to see my first attempts last year with my 'za rodinu' mig 7 build, thanks to Sean and others for contributing to my build with this awesome build log! I'll be building another soon due to damage being incurred due to many heavy landings in die Kaap, I love the South Easter!

Very nice! I've been contemplateing doing the next one white with that scheme for a while now, but was worried it would look too plastic and not scale enough. But that puts my mind at ease for sure.
Mind you, that'll be a while away as the 'Красный Дьявол' (or 'Red Devil') as I've christened it, is still flying beautifully and proving to be a hit with my fellow flyers, as well as gaining the prestigeous position of 'ultra favorite' for myself! It's amazing to think how skeptical I was initially, considering how much I love flying this plane. Must get some vid for you all.

Howzit John,
Cool vid!! thanx!
I enjoyed your ""undercarrige" at the start of the clip!.....three leg potjie!
You guys in ""die Kaap"" are spoilt rotten with those awesome slopes, views and wind!!

Mig

Hey there Sean, my friend and I in Brisbane would very much like to make one of these Mig's. We have a slope that faces the ocean and a landing strip as wide as a ping pong table and as long as a cricket pitch. Otherwise it's the road... Our local hardware has some core flute. But I was thinking about doin a night mission around town and find a few freebies.... You guys are doin a great job.

re cape town mig

Eish, super blessed with the wind and slopes.....at times. Went hiking around Kalk bay yesterday (inspired by vid posted recently), mig in hand looking for wind, that was there, but not there. 2 hrs solid hiking, no flying!
Thanks for encouragement, first (failed attempt-servo reversed, oops) Hout bay, second top of Ou Kaapse weg (bit bumpy), third and best Constantia Neck, though about 35min hike.
JMSR go 'za rodinu'!, def a classic russian look.

Hope u guys in PE got wind this wk end, i should be out flyin but nothin this side.
Ps. I chatted to Ulrich in Somerset West (bit far to meet up for quick slopefly), but if anyone building corro in Southern suburbs of Cape Town, would be cool to meet up.

coreflute grain

I have a question and I have managed to read about 3/4's of this thread. My brain can't take another sentence. Does the grain of the corflute need to run chord wise on the wings? It just seems it would flow better going span wise. I mean to cause no offence, I just ask in case there was something that I may have overlooked in the build process.

Howzit lemuel!!??
Sounds like you need to fly correx!
I am surprised that in many places around the globe, correx is not easily available. I say this cause we live in the armpit of the world and it is dirt cheap and is found all over our little town!
But go ahead with what you have and post some pics!

It can run either way.
Conventional coreflute wings run the flutes cordwise and use the spar to give an airfoil and have a sharp, creased leading edge. See www.spadtothebone.com for designs.

I prefer to run them spanwise and use ribs and a rolled leading edge. This gives a truer airfoil and allows use of the flutes to hinge the ailerons. It also gives a torsion-ally very stiff wing on a tapered form as top and bottom sheets run diagonally in opposing directions when the wing is folded and the flutes give good spanwise stiffness without a spar.

Span wise it is then. The triangular shaped foil works, but I guess old habits die hard. Also, I was thinking about using core flute for the formers also. Maybe doubled up?

all of the MIG wings built here in PE have the flutes running chord wise, the resulting wing profile is not a triangle, it is almost flat on the bottom, with maybe a bit of under-camber depending on how the trailing edge is clamped during folding and gluing. I have experimented with letting the Leading Edge rise up a bit off of the table during folding, but find the "flat bottom" wing gives the best all around performance. The sharp leading edge doesnt seem to result in any strange pitch moments like you might expect.
